Madonna can be many things. This song conveys an epic story of love, truth and regrets. I don't quite know what it's about, but I find myself being swept up in a profound tale she is telling. Maybe that's secondary. The song is just as much about what a great voice she has. A lot of her other music doesn't convey this. She has various musical guises but she has a glorious voice not always obvious in her other songs. Also, the arrangement is neat in how the song comes nearly to a stop in the middle, and then starts up again, reaching an emotional pitch a second time. It has great synthesizer too.
